UNITED STATES PATENT OFFICE 2 Claims.

The present invention relates to revolvable stools, and has for its mainobject the provision of simple and inexpensive revolvable mechanism bymeans of which the stool seat may revolve with relation to the stoolbase.

A still further object of the present invention is the provision in arevolvable stool of a pair of ball-bearing races, one attached to thebase and the other to the seat section of the stool, with ball-bearingsinterposed between the races, for ready revolving of the seat section ofthe stool with relation to the base thereof, with means for maintainingthe races connected on a vertical plane and in transverse relation withthe base and the seat section.

With the above general objects in view and others that will appear asthe invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts hereinafter morefully described, illustrated in the accompanying drawing and pointed outin the appended claims.

In the drawing forming a part of this application, and in which likedesignating characters re fer to corresponding parts throughout theseveral views;

Fig. l is a diametrical cross-sectional View, on a vertical plane,through the support, base, seat section of the stool and revolvableconnection between the base and seat section of the stool;

Fig. 2 is an enlarged, fragmentary, cross-sectional view, similar tothat of Fig. 1, Showing re- Volvable connection between the base and theset section of the stool; and

Fig. 3 is an enlarged, fragmentary cross-sectional view on line 3-3 ofFig. 1.

Referring in detail tothe present drawing' there is shown therein stoolsupporting standard I Il, which by its lower end may be rigidly affixedto a floor. Rigidly ailiXed or integrally formed with the upper end ofsaid standard IG is a circular base II. Positioned upon upper face ofbase Il, and centrally thereof is washer I2 which is rigidly aflixed tosaid base I I by any suitable means, such as welds I 3. Positioned uponthe upper face of said washer I2, and rigidly affixed thereto bywelding, as at I4, or any suitable means, is lower ball-bearing race l5.Super-imposed over said race I5, in a cooperative relation therewith, issimilar raee I6. Said latter race I6, by its upper face is rigidly afxedby any suitable means, such as welds Il, to washer I8. The latter isaffixed to the under-face of seat base I9, by being welded thereto as at2B, or by any other suitable means.

Races I5 and I5 are in a mutually spaced relation, and on their opposedfaces are each provided with annular channel 2 I, each of which is of anarcuate formation on transverse cross# section, for seating a pluralityof ball-bearings 22, the latter being interposed between two races I5and I6, and are there Vretained in an operative and spaced position bymeans of a conventional ball-bearing supporting ring 23. The latter isprovided with conventional openings 24! within which ball-bearings 22are seated in a transverse relation with ring 23.

The corner of each race the outer face of each race riphery thereof isreduced for effecting bevel 25. Placed around the two races and incontact with their outer peripheries is cylindrical member 26, havingits ends inwardly flanged for effecting inwardly directed lips 2l, eachof which overlies and contacts with the respective bevel 25 in races l5and I6.

It is noted that the engagement of cylindrical member 26 with races I5and 'I6 is accomplished before the latter are aiiixed to washers I2 andI3, respectively, and before lips 2l have been formed. This is done byrst inserting races I5 and `It with ball-bearings 22 and ring 23 in theoperative position between said races, as best shown in Fig. 2, andthereupon spinning over the ends of said cylindrical member 25 towardsbevels 25 until lips 2l are formed and brought in an operativecontactual relation with bevels 25 as is seen in Fig. 2. Thus, When saidlips 2l have been formed and engaged with said bevels 25, races I5 andI5, ball-bearings 22 and cylindrical member 2S will constitute a unit tobe interposed and rigidly affixed by welds I4 and Il to the respectivewashers I2 and I8.

Lips 2l, contacting with bevels 25, prevent separation of races I 5 andi 5 in vertical direction, but the contactual engagement of cylindricalmember 26 with the peripheries of races I5 and I6, and of lips 2l withbevels 25, is suificiently loose so as to permit free and unobstructedrotary motion of one race with relation to the other, the rotary motionof said races is facilitated by ball-bearings 22. Before cylindricalmember 26 is applied to races I5 and I6 a lubricant may be spreadbetween said races and channels 2|, as well as upon ball-bearings 22 forthe purpose of facilitating free rotation of races I5 and I6 withrelation to each other. The inner periphery of cylindrical member 26 maylikewise be lubricated before the insertion therewithin of said races I5and i6, for facilitating rotation of said I5 and I6, defined by and theadjacent pe` races with relation tosaid cylindrical member 26. Spongerubber cushion 23, or cushion made of any other suitable material,positioned and attached to seat section I9 of the stool, completes thestructure of the present invention. Parts other than said cushion 28 arepreferably made of any suitable metal. It is understood that weldingconnections I3, It, I'I and 29 may be eliminated and bolts, screws orany other suitable means may be substituted therefor.vr Y v f From thehereinabove description it will be apparent that due to the revolvableYconnection between base II and seat section base I9, throughl themedium of races I5 and IG and cylindrical member 26 joining therewith bymeans of bevels 25 and lips 21 the seat section of the stool c'annot bedetached or removed frombase II, while permitting complete rotarymovementof' the seat section of the stool with relation to base Iil, thelatter through the medium of ball-bearings 22 and races IE-andli. v Y

It is further observed thatbase II may be unattached to any support suchas standard I, and further said base may be enlarged to conform to thediameter of the seat section base It, and

when thus constructed the entire stool unit may'- be easily carried andwhen in that condition the stool may be used for boats as a seat to beplaced upon boat benchV to be used while fishing or operating amotorhwith full vfacility forthe user for turning in all directionswithout changing the yseating position with relationto the stool.-

It yis alsonoted that washers I andV I8 may be entirelyeliminatedinwhichcase1races rl 5 and I t may be directly afxed lto stationary base IIHand seat base I9, respectively.: For all-practical purposesrwashers I2and -lniay be consideredy as parts of stationary base II and seat baseIgyrespectively. A I 'Y While there is described bodiment of the presentinvention,l it is nevertheless to be'understood that minor `changesmaybe made thereinwithout departing'from the ,spirit and scope o f theinvention as claimed. 1- What I claim as newis:

1. A revolvable stool compri base,A a'race rigidlyfaflixed to saidbase,a seat base in a spaced relation `witl'isaid stationary equal diameter,anti-friction elements interposed base, a race rigidly aixed to saidseat base, the two races being'of anpannular formation and of herein apreferred em# sing Va stationary 'for permitting free rotary movement ofone race with relation to the other on a horizontal plane,

for permitting rotation of said seat base with relation to saidstationary base.

2. A revolvable stool comprising a stationary base, a race rigidly aixedto said base, a seat base in a spaced relation with said stationarybase, a race rigidly aixed to said seat base, the

vmember being bent toward the longitudinal two races being of an annularformation and of equal diameter, anti-friction elements interposedbetween said races, and a cylindrical memberV surrounding said races andin contact with their outer peripheries, the ends of said cylindricalcenter of said cylindrical member for effecting lips, said lipscontacting with and overlying the portions of the outer end faces ofsaid races adjacent their peripheries, said lips and said antifrictionelements constituting means for maintaining said raees in a rigid mutualrelation transversely thereof, and for permitting free rotary movementof one race with relation to the other on a horizontal plane, forpermitting rotation of said seat'base with'relation to said `stationarybase.
